Abstract: Current application of large number of commercial asparagus bean cultivars with very high genetic similarity caused more and more disputes on seed quality. In this research, a set of SSR markers for asparagus bean were developed based on a bioinformatics-based approach. Ten of these markers were defined as diagnostic markers by genotyping a core collection of asparagus bean consisting of 44 lines. Based on this, a rapid and precise SSR-based procedure for asparagus bean seed quality surveying was established, which would meet the demand of rapidly developing asparagus bean industry.

Key words: asparagus bean, SSR, purity surveying, genetic fingerprint
